Nortel E1 QSIG Trunk Integration
Please note the following regarding Nortel E1 QSIG trunk integration:
•
Noise on the PRI link might indicate an incorrect PCMU configuration of PRI
trunks on the CS 1000. The
PMCU
should be set to
A-Law
for E1.
•
When there is an E1 link between CS1000 and the EasyCall Gateway, the end
user may experience that the E1 link is up and down continuously. This might be
caused to a mismatched multi-frame format configuration between CS1000 and
the EasyCall Gateway. The procedure in “Defining PRI Parameters and
Threshholds” on page 30 may help to resolve this issue.
The following topics describe a sample configuration of Nortel Telephony (PBX)
system integration with the EasyCall Gateway through an E1 ISDN-PRI QSIG trunk.
